Is there a thirdy part interface to do a repeater with 2 gm900 using mic connettor and/or db25 accessory connector? ...
I saw on the web some integration with "Communications Specialists, Inc. TP-32OO SHARED REPEATER TONE PANEL" as repeater control unit.

Anyone have done this type of modification to this radio?
Waiting your answers
